Check out Planet 14, it's worth the walk.
Uber to PHOF and then walk back, grab some beers at the gas station for the walk. It's fun to watch the planes landing as you're walking.
Atomic Saloon was a great show, from the same company as Absinthe, just way cheaper since it's new
Red rocks is a blast. Take an uber there and back, just meet them and have them drop you off before the line at the main road, otherwise you just sit and wait in line. You can get wifi at the main building, but otherwise there's really no signal out there.
If you like beer, just buy large cans at walgreens and CVS. $3 for 24oz and you're good until you hit the next one while wandering.
